. 4IllIPROVIEIlEN'I IN VENTILATORS FOR BATS.

Y' Litige tlgchle etant tu im tiges: ttets @that :mt mating part rf tigetame TO A'LL W'HOM IT MAY CONCERN Be' it known that we, WILLIAM M.IRVINE and ALFRED H. MOSES, of Montgomery, -in the county of Montgomery,and State of Alabama, have invented certain new and usefulImprovements'in'- Hats; and we do hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawings, and to the lletters oi' reference marked thereon,which form a part of this specieation, and in which- Figure 1 representsa plan 'view of a hat with our improvement attached, and

Figure 2 is a perspective 'of the band. Y v

A band of metal, A, or other suitable material, about one inch wide,is'formed into a ring to suit the shape of the head. One side ofthe bandiswpunched with small holes, c c, suitable for sewing the band or ringto the inside of theside of a hat. The band is divided into two pieces,by cutting it at both sides, a little in front of the centre; we alsoseparate the band in front and' baclr, and hold the parts together bybuttons a a, as shown in iig. 1.

The front portiu of a band, A, Hg. 2, has a longitudinal slot, C, neareach end, about one-eighth of an inch wide, and about one inchlong. Oneend of the band B is' perforated with a hole, to allow a small screw, e,to pass through; the screw also passes through theslot, and screws intoand through a nut on the outside of the slot, inthe end of the bayd A,at C, when the ends-of the bands are `lapped over each other. @.Theother end of the band B has a slot about one-eighth of anf inchwidemandan inch long. .,The end ofthe band runs into afat tube, E', theftubebeing firmly secured to the hat bysewing or otherwise. rI he end of thetube is perforated by a small hole, to allow a screw to pass through.The screw passes through slot in end of band B, and into a nut onoutside of tubo E. The screws e, which pass through the ends ofthe bandA at C, reachfnearly to the inside of the hat. A long nut,'perforated bysmall holes in its sides, to admit lthe point of an instrument forturning it, ts over each of the screws at C.

The brass tube E has an ear at one end, which is pierced with a smallhole to allow a screw, d, to pass through, which screw also passesthrough slot C, in end of band A, and into a nut on outside of slot.

v When the band or pieces of band are sewed in thebhat onthe sides of`the inside, a space for ventilation is left between thephat and theband, both in front and behind. The band comes in direct contact withthe sides of the hat.

When complete, the band may he covered with leather or other suitablematerial, in which small holes are left for the purpose of working thescrews.

Mode of. Using.

By loosening the screws whichl pass through the slots in thepieces ofband, the size of the ,ring may be increased or diminished, to suitheads'of different sizes, and secured in place by again tightening thescrews.

By taking out the screws which pass through the slots (l C, the frontportion of band A may be entirely lremoved, and the requisite pressureon the temples to snpportthe hat may be' obtained, by turning the nutsonscrews, which pass through end of band B and` ear'of tube E; or byloosening the screws which pass through slots C C, the `portion of bandA may `bc turned up at or nearly at right angles, adjusted and securedbyv again tightening the screws, injvhichposition it would still bear aproportion of tho weight of the hat b y resting on top ofthe head; theobject being in both cases to support the hat comfortably on the head,without any portion ofit coming directly in contact with the forehead.

We do not claim a simple ring or hand when used inside of a hat forventilation.

Claims.

LIWe claim aband or ring so constructed and arranged ou the; inside of ahat that itV may be adjusted to different-sized heads, substantially asdescribed. l I

2. We claim the band A, constructed in either one or more parte, andfurnished with tubes e and a, slots C, and tube E, allarranged in themanner and for the purposes set forth.

In testimony that we elaimtho foregoing as our own, we aflix oursignatures inthe presence of two witnesses.
